What's everyone using for speakers these days? I still have my Polk Db651's in the fairing and Db521's in the rear pods, but they just don't sound as good as they used to. I'm guessing that 2.5 years of heat, sun and getting caught in downpours is starting to take its toll on them, either that or my hearing.. I've heard the the Polk MM652's are a good choice, but haven't heard them. I did go to the local big box store and the best sounding 6.5's they had were JBL GX602's, but they're not marine rated (not sure how important that is). Not sure what I'll do in the pods yet, haven't thought that far ahead. Thoughts?
